Some days you don't know what to say in your caption. No matter how much brainstorming you do, your ideas feel flat, uninteresting and you skip posting all together.
And on those occasions when you've got an idea you feel good about, and the writing actually flows, the formatting looks like one long run-on sentence. So instead of typing your caption directly into Instagram™, you type it into a Note on your smart phone. But once you cut and paste it? You still have to add in paragraph breaks and spaces.
